INSPECT CYLINDER HEAD SET BOLT
Using a vernier caliper, measure the minimum diameter of the elongated thread at the measuring point.
| Standard outside diameter |
|---|
| 10.85 to 11.00 mm (0.427 to 0.433 in.) |
| Minimum outside diameter |
|---|
| 10.6 mm (0.417 in.) |
| Measuring point |
|---|
| 90 mm (3.54 in.) for intake side bolt |
| 85 mm (3.35 in.) for exhaust side bolt |
Tech Tips
If a visual check shows no excessively thin areas, check the center of the bolt (see illustration) and find the area that has the smallest diameter.
If the diameter is less than the minimum, replace the cylinder head set bolt.
INSTALL NO. 2 CYLINDER HEAD GASKET (for Bank 1)
Place a new No. 2 cylinder head gasket the cylinder block surface with the Lot No. stamp facing upward.
Note
Be sure to place the gasket in the correct direction.
Gently place the cylinder head on the cylinder block in order to prevent damaging the gasket.
INSTALL CYLINDER HEAD SUB-ASSEMBLY (for Bank 1)
Place the cylinder head sub-assembly on the cylinder block.
Note
Clean and degrease all contact surface.
Inspect and clean each cylinder head set bolt and installation hole.
Apply a light coat of engine oil to the threads and under the heads of the cylinder head set bolts.
Tech Tips
Tighten the cylinder head set bolts in 3 progressive steps.
Step 1:
Using a 10 mm bi-hexagon wrench, install and uniformly tighten the 10 cylinder head set bolts with the plate washers in several steps, in the sequence shown in the illustration.
Step 2:
Mark each cylinder head set bolt head with paint as shown in the illustration.
Tighten the cylinder head set bolts another 90° in the sequence shown in step 1.
Step 3:
Tighten the cylinder head set bolts by an additional 90° in the sequence shown in step 1.
Check that the painted marks are now facing rearward.
Install the 2 bolts in the sequence shown in the illustration.
Place the camshaft housing on the cylinder head sub-assembly.
Temporarily tighten the camshaft housing with the 3 bolts in the sequence shown in the illustration.
Fully tighten the 3 bolts in the sequence shown in the illustration.
